SAFETY-LOCK FOR GUN-LOCKS- Specification of Letters Patent.

PatentedApril 3, 1906.

Application filed February 16, 1904. Serial N- 193,793.

To aZZ whom, it may concern:

Be it known that we, MORGAN P. Roenns and ERNEST C. RoUsE, citizens of the United States, residing at San Jose, in the county of Santa Clara and State of California, have invented new and useful Improvements in Safety-Locks for Gun-Locks, of which the following is a specification.

Our invention relates to improvements in firearms, and particularly to means for looking the lock of the firing mechanism to prevent accidental discharge.

The object of our invention is to provide means for securely locking the lock itself, so that whether the trigger is pulled or the gun dropped or thrown down discharge will be impossible.

The invention consists of the parts and the construction and combination of parts, as hereinafter more fully described, having reference to the accompanying drawings, in which Figure 1 is an elevation, partially broken away, of the operating parts of a gun-lock, showing the application of our invention as affecting the sear. Fig. 2 is a cross-section on the line 00 as of Fig. 1.

A represents the frame of a shotgun of or dinary construction; 2, the lock-plate; 3, the tumbler or hammer; 41, the mainspring; 5, the sear; 5 the bridle cooperating with the lockplate as a support and guide for the hammer, mainspring, and sear; 6, the triggers 7, the sliding plate for shifting the safety device, and 8 the thumbpiece for actuating the safety.

With an ordinary double-barrel shotgun the several parts of the lock are duplicated and each sear carries an inwardly-projecting arm 9 at its rear end extending into the path of the triggers. WVhen a trigger is pulled, the arm 9 of its corresponding sear is engaged to rock the sear on its pivot 10 and,

providing the piece is cooked, moving the front end of the sear out of the notch 11 and releasing the hammer. Obviously a safety attachment applied only with the idea of preventing the pulling of a trigger still may leave the sear to oscillate and disengage its notch 11 and the mainspring free to act with full force on the hammer. In'order to lock the sears, we provide a stud 12, which has its lower end suitably pivoted to permit it to have a limited lengthwise movement, and its upper end fitting a hole in the safety-slide 7 and movable into and out of line with the recesses or pockets 14 15 in the tang 20. In the present instance We have shown the lower end of the stud as pivoted in the slots 21 of the trigger, so that the triggers, as well as the sears, will be locked against accidental movement, as will be seen. The stud carries the lateral projections 16, disposed in the path of the sear projections 9, and are adapted to lock the sears against movement except when the stud stands in line with one or the other of the pockets 14 15. A spring 13 bears against the under side of the slide 7 and against the parts 16 to press the stud normally downward. When the slide 7 is moved to bring the upper end of the stud into line with one or the other of the recesses or pockets 141 15, the trigger may be pulled to discharge the gun. When the stud is in intermediate position between the pockets 14 15, the projections 16 engage the upper side of the sear projections 9 and the stud-pivots bear against the bottom of slots 21, so that neither the triggers nor the sears can be moved, and the parts are then in the position of safety. The slide 7 is held in any desired position by means of the boss 17 engaging one or the other of the notches 18. The thumb-piece 8 has its stem extending loose through slide 7, and a spring 19 acts to press the slide always up against the tang 20.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is' r 1. In a gun, the combination with a hammer, a mainspring, a sear and a trigger, of an oscillating stud pivoted to the trigger and having a part interposable in the path of the sear to lock the latter against movement.

2. In a gun the combination with a hammer, a mainspring, a sear and a trigger, of a stud pivoted to the trigger and adapted to have a limited oscillating and a limited reciprocating movement, said stud having a projection interposable in the path of the sear, and means for operating the stud to cause it to lock the sear against movement.

3. In a gun the combination with a hammer, a mainspring, a sear and a trigger, of a depressibie part carried by the trigger and set our hands in presence of two subscribing having a part interposable in the path of and Witnesses.

engageable with the sear to lock the said sear MORGAN P. ROGERS. j against movement, and means for releasing ERNEST C. HOUSE.

5 the depressible part to cause it to restore the Witnesses: sear into operative condition. Tnos. BoDLEY,

In testimony whereof We have hereunto W. J ROGERS.
